SUPPLY VALVE FUR DRfINKING FOUNTAINS.

Original application filed November 12, 1919, Serial I Io. 337,490. Divided and this application filed October 15, 1923.

To all whom it may concern:

Be it known that PHILIP MUELLER and ANTON G. SCHUERMANN, citizens of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Supply Valves for Drinking Fountains, of which the following is a specification.

The present invention relates to a supply valve and operating mechanism therefor, which is particularly adapted for use with drinking fountains of the pedestal type, a

preferred form of which, is set forth in applicants copen'ding application, Serial No. 337,490, filed November 12, 1919, (Patent No. 1,490,677, Apr. 15, 1924), of which this case-is a division made under ofiicial requirement.

Primarily, the invention consists in providing a valve bod with an adjustable valve operating mec anism so disposed as to be readily accessible for the purpose of necessary adjustment to the valve and its associated parts. The operation of the valve is effected by a pedal disposedoutside of the valve housing, and so arranged upon depression thereof, to move the valve from its scat, thus permitting the -water to pass from the supply pipe through the cock body.

' In order that the valve may be operated by children as well as adults, a lever means is provided for actuating the valve from any desired level.

A further advantage of the present developmentresides in disposing within the valve body, a regulator and stop mechanism arranged opposite the valve opening so that the supply may be controlled or entirely stopped as may be deemed necessary.

In the drawings herewith, we have illustrated one embodiment of our invention:

Figure 1 is a sectional view of a fountain disclosing our invention,

Figure 2'is a detail sectional view of the supply valve operating lever and regulator screw,

Figure 3 is an end elevation partly in section of the supply valve, showing one form of hand hole cover, v

to the bubbler head (not shown) is vertically disposed within the offset waste 18 and is connected to the supply section 15 by an elbow coupling 19.

A valve stem 20 longitudinally disposed within the cock body 14, is formed at its inner end with a shouldered recess portion, to which is threadedly secured, by the screw 21, theseat washer 22. A closure cap 23 threadedl secured to the cock body 14, is so forme as to provide a shoulder for the spring 24, which surrounds the stem 20, and normally tends to force the washer 22 into the valve seat 25.

A diametrically disposed pin 26 secured to the valve stem 20, is adapted to engage corresponding slots arranged in the interior wall of the cap 23 so as to prevent relative rotation of the valve stem with'respeet to the cap.

A stuiiing nut 27 through which the valve stem 20 passes is threaded to the cap 23 and maintained in tight connection therewith by the. acking 28. The stuflin nut 27 is preferab y held against accidenta displacement by the lock finger 29 which engages the hexagonal periphery of the said nut.

the stem, it is locked by the pin. 33 against accidental rotation. I

To the underside of the cock bod 14 is. attached an arm '34,'- to the free end 0 which is pivotally secured b the pin 35, the arms 36 of a forked peda lever 37, havin its outer extremity terminating in a peda 38,

The inner end of the lever 37 is provided with outwardly extending lugs 39 adapted to be engaged between the flanges 31.

It will be apparent that upon the application of the foot to the pedal extremity 38 and the pedal lever being rocked on its pivot 35, the lugs 39 connected with the adjustable sleeve 30 will cause the valve 22 to be re- 1 moved from its seat, at the same time compressing the spring ,34, and thus permit water to pass from the supply pipe through the cock body to any suitable source of supply. It will be observed that upon release of the pedal, the valve will be automatically shut off by the expansion of the spring 24.

In order that the supply may be regulated or entirely out 01f, if necessary, there is provided a regulator screw or stop 40 threaded to the interior portion of the cock body 14, on the opposite side of the valve seat and in direct alignment with the valve stem. A packmg 41 and gland 42 are arranged within the body of the cock and secured thereto by the adjustable nut 43. The outer end of the screw 40 is formed so as to receive a wrench or other suitable tool to permit adjustment of the regulator. In order to prevent accidental displacement of the screw 40, a stop finger 44' similar to the stop 29 previously described, is provided so as to engage the serrated portion 45 of the stop screw.

In order to provide an installation which may be used by children as well as adults, without the necessity .of changing the essential parts of the operating mechanism, we provide a second valve operating pedal 46 formed with arms 47 which are adapted to be pivotally engaged to the cock body 14 by the pin 48. The arms 47 further provide a lifting toe which contacts with a projection 49 on the adults pedal 36. The outer end of the childs pedal 46 extends through a slot 50 in the lower portion of the pedestal 10 and is pivotally connected to a push rod 51 which is operatively connected at its upper end to the floor of a childs stand (not shown).

It will be seen that upon depressing the outer end of the childs pedal 46, the arms 47 will lift the projections 49 of the adults pedal 36, and operate the valve exactly as it is operated when the adults pedal is depressed. It is, of course, apparent that no operation of the childs pedal is accomplished when the adults pedal is manipulated.

In order to provide ready access to the cock body and to permit adjustment of the stop and regulator to the valve and pedal parts, a cover plate 53 is arranged to cover the circular opening 54 in the wall of the pedestal and is removably secured thereto by the cross bar 55 and the threaded nut 56, provided at its forward end with a hex agonal head as shown. It will be observed that the regulator screw 40 is in line with the hand hole screw 56 and preferably we provide a single wrench for rotating both the regulator screw 40 and the screw 56 of the cover plate, thus obviating the necessity of providing different wrenches for manipuating these two parts.

In the form of the invention disclosed in Figure 3, a similar construction to that heretofore described is shown, except that no provision is made for the childs operating pedal, it being designed to have only the adults operating lever 57, and a different type of cover plate than that disclosed in Figure 1, the cover plate being of the form of a box 58, the lower end of which is provided with lugs 59 which rest upon the pedestal with the upper part of the housing conforming to the pedestal wall, and enclosing the recess 60 in the pedestal wall, through which the stop and regulator portions of the cock body extends. The cover plate 58 is anchored in place by means of the clamping bar 61, the inner end of which is bent as shown to engage the wall of the pedestal and the outer endis arranged to be seated in a box 62 formed by ribs on the inner side of the cover plate. A clamping screw 63 extends through the top of the cover plate. and threa edly engages the clamping bar 61, so that when the cover plate or housing has been set in position and the clamping bar drawn up by means of the screw, the housing 58 will be locked firmly in place. With this arrangement, the cock body and its associated parts are very readily accessible for adjustment and repairs.

The stop and regulator disclosed in F gure 4 are slightly varied in construction from that heretofore described. This construction comprises the long screw 64 having a threaded engagement of suitable length with the cock body and) being ar ranged opposite the valve seat. The screw 64 is provided with a head 65 adapted to be engaged by a screw locking pawl 66 pivoted on the cock body so that when the screwhas been adjusted the pawl may be dropped into locking engagement so as to prevent accidental rotation and eliminate all possibility of disarranging the regulated supply. The stop regulators thus descrlbed are entirely enclosed by means of a cap 66 which is threaded to the exterior portion of the cock body, as shown and which is of wrench formation so that it may be turned by hand or a suitable tool after the cover plate has been removed.

It is to be understood that this disclosure is merely illustrative of several preferred embodiments of our invention, and that such changes in design and substitution of mechanical-equivalents for the various exped1- QQ I Pli lP abedw 1 2 1 1 sane closed "valve thereiffi a forked va ents disclosed, may be made without depart ing from the spirit of the invention and the scope of what is claimed.
